These brushes simulate graphite/pencil in photoshop.
There are 2 types of brushes, 'sketchy' and smooth. There are angled and round versions of each.
I intended these to be used by people who want to use Drawing Tablets in Photoshop, but they can be used with a mouse as well. However, you won't be able to benefit from the Pen Pressure settings.
Make sure you put your colours as default-- Black and White, or set the top colour for whichever hue you'd like, I find that darker colours produce a better result.
If you'd like it to 'build up' like a real pencil you should have the brush set to Darken and/or lower the opacity.
If you want to make these seem more "H" or "B" just go to brush settings and toy with the opacity, flow, and fore/background jitters.
For photoshop 7 or below, go to [link]
and look at the options for the brush. You can make your own- sorry, I don't have photoshop 7 but if someone wants to make these compatible go ahead just make sure to link back!
